in early 1900s, Captain Rodger's anchors marked a great departure from the form of previous design anchors.
The arms were formed in one piece, and were pivoted at the crown on a bolt passing through the forked shank.
The points or pees to the palms were blunt. This anchor had an excellent reputation amongst nautical men of that period and by the committee on anchors, appointed by the [British] admiralty in 1852, it was placed second only to the anchor of Trotman.
